Enum PluginError 

pub enum PluginError {
    IllegalName(String),
    Duplicate(String),
    UnknownDep(String),
    DepCycle(Vec<String>),
    UnknownName(String),
    Stopped,
}

宿主注册/生命周期错误。

0.2.0 变更:移除 HostStarted 变体——运行期动态 add 合法(新 D1); 仅 Stopped(宿主已 close)仍拒绝一切变更。

Variants

IllegalName(String)

插件名不合法(规则:首字母字母,其余 alnum/_/-,长度 1..=32)。

Duplicate(String)

重名注册。

UnknownDep(String)

deps 指向的目标在 start 时不存在(add 期不再校验——解耦注册顺序)。

DepCycle(Vec<String>)

start 时 deps 构成环(列出环上点名)。

UnknownName(String)

get/remove 等操作目标不存在。

Stopped

宿主已 close():一切变更被拒。

impl Eq for PluginError

impl Error for PluginError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
